An integrated security control system and method which integrate the functions of a wireless security system control panel and a radio transceiver in an integrated security control system unit. The integrated control unit includes a first telephone communication system for communicating security system data by wired telephone communications, and a second radio frequency (RF) cellular communication system for communicating security system data by communications through an RF communication network. The cellular communication system is the primary communication network for reporting a security event, thereby leaving the first telephone communication system open for telephone communications during the reporting of a security event. A separate unit of the security system, such as a wireless RF status display or a wireless RF keypad, is provided with a beeper transducer for sounding entry and exit beeps. The separate unit is positioned at a separate location from the integrated security control system unit, such that the entry beeps do not alert an entering person to the location of the integrated security control system unit. When a security event is triggered, the control unit delays activating a security alarm sounder in the control unit until after the second RF communication system has finished transmitting the alarm message.
